Building high-performance web & mobile applications across healthcare, logistics, telecom, and e-commerce
I'm a Senior Software Engineer with 7+ years of experience crafting production-grade web and mobile applications. My work spans across healthcare, e-commerce, logistics, AR/3D visualization, and telecommunications — delivering scalable frontends and cross-platform mobile apps that actually ship.
I work comfortably both as an independent contributor and as part of cross-functional distributed teams, having collaborated with companies in Indonesia, Singapore, Hong Kong, and the United States.
